The Roman Army was made up of men from all over the Empire, no women were allowed to join. These men wereprofessional soldiers whose only job was to fight and defend Rome. Initally only property owners such as farmers could serve in the army, but from the 1st century B.C. onwards anybody could join. These soldiers would have to stay in the army for at least 25 years!
If a soldier was brave, clever and fought well he could become a centurion in charge of 80 ordinary soldiers called legionaries. Each troop of about 80 legionaries was called a century. There were 59 centuries in a legion and about 30 legions in the Roman army. There were also other soldiers called auxiliaries who included the cavalry.
Hasta: The hasta was the Roman trusting spear. It was carried by the unitscalled triarii in Republic times. Marius military reforms made the pilum the standard spear carried by all legionaries.
Pilum: The pila (plural form) were quite unique in design. These javelins were designed to warp after impact, so they would drag down an enemy's shield, sometimes pinning two of them together. The average pilun was 1.8 meters long. It had a barbed iron shaft connected to the wooden pole in a weighted socket.
